H Application fiieanuy s,

T 0 all whovn it may 00mm Be it known that I, JoHNA." AM N citizen ofthe United States, residing. at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inEqualizing Trucks of which the following is a specification.

This invention relates to equalizing trucks for railway cars and of thesix-wheel type.

One object of the invention is to provide a simple and eiiicientequalizing arrangement for railway car trucks which will transmit theloads in a manner such that the intermediate journal box will have notendency to tilt and cause excessive wear of the parts, but willmaintain said journal box in a central position to function in a normalmanner at all times.

Another object isto provide an equalizing arrangement for six-wheel cartrucks adapted to meet the various requirements for successfulcommercial operation.

These and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheets of drawings, in which- Figure 1 isa fragmentary longitudinal sectional view of a railway car truckembodying my invention, some parts being. shown in elevation;

Figure 2 is a sectional View taken in a horizontal plane through a sideframe show ing cooperation of associated parts.

Figure 3 is a sectional view taken in the plane of line 33 of Figure l;and

Figured is a sectional view taken in the plane of line 44 of Figure 1.

h The various novel features of my invention will be apparent from thefollowing description and drawings and will be particularly pointed outin the appended claims. Referring to the figures of the drawings, itwillbe noted that I have disclosed my invention in connection with arailway car truck of the six-wheel type having aside frame 10 with anopening 11 for the reception of an intermediate journal box 12, thejournal box being guided in its relative vertical movements with respectto the side frame by side walls 13, the latter being provided withhardened steel wearing plates 14 for minimizing the wear. This ournalbox 12 has spring pockets 15 at either side of the main portion of thebox in which the journal 16 particularly to trucks 0F NEVTJERSEY.

is located. Load carrying springs'17 are mounted in these pockets andare bridged by a spring cap 18 having a central arched portion 19 forthe reception of a yoke 20. This yoke has depending arms 21 which extenddownwardly through openings 22 in the spring cap 18, through the coiledsprings 17 and through openings 23 in the floor of the spring pockets.The lower ends of the arms 21 of the yoke 20 are provided with openings24 for the reception of pins 25 upon which a hanger 26 is slung. Thishanger has two upstanding arms, the walls of which are spaced for thereception of the lower ends of the yoke arms 21 and are provided withopenings 27 which also receive the pins 25. Pivotally mounted in thelower horizontal portionof the hanger bracket 26 is an equalizing beam28 upon which the inner ends of the cooperating equalizing levers 29directly rest. The outer ends of these equalizing levers 29 arepivotally mounted, as

' shown at 30, and receive their loads through I positiom'any tendencyfor the journal box to tilt thereby being overcome. Also any abnormalwearing of the parts which would be occasioned by a tilting of the boxis obviated.

It is my intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

I claim:

1. In a railway car truck, the'combination of a journal box, anequaliz'ng beam mounted below the journal in said box, and equalizinglevers operatively connected to said beam whereby the journal box isprevented from tilting.

2. In a railway car truck, the combination of a journal box, anequalizing beam mountedbelow the journal in said box, and

equalizing levers connected to said beam. at

journal in said journal box for preventing the latter from tilting.

4. In a railway car truck, the combination of a journal box, a membersupported thereby, an equalizing beam pivotally mounted on saidmemb'erbelow the journal in said journal box, and equalizing levers fortransmitting loads to opposite ends of said equalizing beam. j

5. In a railway car truck, the combination of a journal box, springscarried thereby, spring cap bridging said springs, a yoke carried bysaid spring cap, a hanger slung from sa d yoke, an equalizing beamcarried by said hanger, and equalizing levers operative-iy connected tosaid beam.

(5. In a railway car truck, the combination of a journal boX havingspring pockets,

springs mounted therein, means bridging said springs, means suspendedfrom said bridging means, means slung to said suspended means, anequalizing beam carried by said slung means, and equalizing leversoperatively connected to said equalizing beam.

7. In a railway car truck, the combination of a journal box, resilientmeans carried thereby, means supported by said springs, means slung fromsaid spring supported means, an equalizing beam supported by said slungmeans, and equalizing levers operatively connected to said equalizingbeam.

Signed at Chicago, Illinois, this 6th day of July, 1921.
